Nearly one-third of those who died in car crashes in B.C. were not wearing a seatbelt, according to the BC Coroners Service.

In a report released Thursday, the coroner said 29 per cent of those who were killed in a crash between 2011 and 2016 were not wearing either a seatbelt or a child car seat.

The report found that 71 per cent of women used a seatbelt, compared with just 49 per cent of men.

Men were also more likely to die in car crashes, with 69 per cent of victims being male compared to 31 per cent of women.

The report found 61 per cent of those killed were drivers or passengers, while 18 per cent were pedestrians and 11 per cent were motorcycle riders.

Cyclists and commercial drivers each made up another three per cent of fatalities, and users of motorized scooters made up one per cent.

Alcohol or drugs were factors in 34 per cent of fatal crashes, with more than 50 per cent of drivers under the age of 40 impaired at the time of their deaths.

Despite years of anti-impaired driving campaigns, a full 34% of fatal car crashes involved drugs or alcohol. Young people were more likely to have car crashes caused by impairment, but a breakdown by sex was not available.@BlackPressMediapic.twitter.com/T69eNT0KA5

The summer months were the most deadly; 39 people died in June compared with 24 in December, the deadliest month of the 2018 winter.

The Interior Health region was home to one-third of the 314 people who were killed in car crashes in 2018. The Fraser Health area was the second most deadly at 77 deaths and Vancouver island was the third-deadliest at 49 deaths.
